Closed-Loop Decoder Adaptation Shapes Neural Plasticity for Skillful Neuroprosthetic Control

Abstract: Neuroplasticity may play a critical role in developing robust, naturally controlled neuroprostheses. This learning, however, is sensitive to system changes such as the neural activity used for control. The ultimate utility of neuroplasticity in real-world neuroprostheses is thus unclear. Adaptive decoding methods hold promise for improving neuroprosthetic performance in nonstationary systems. Here, we explore the use of decoder adaptation to shape neuroplasticity in two scenarios relevant for real-world neurop… Show more

“…This concept of simultaneous (or co-adaptive) learning has been proven to be effective also in the context of brain-computer-interfaces ( [17], [18], [26], [27]). Such co-adaptive systems are influenced by the speed with which both learners, the human and the machine, are adapting [18].…”

“…While there has been substantial work in developing adaptive BMI decoders that update their kinematic decoding parameters in response to externally specified errors [31,50,6063] or inferred errors from the statistics of the system’s output [64,65], intracortical BMI designs have not explored the utility of a biological task outcome error signal. A BMI user is typically provided constant visual feedback of the BMI-controlled effector (e.g., computer cursor) and the BMI behavioral goal (such as the target on the screen), and is therefore aware of their BMI performance.…”

“…This goes back to the fundamental questions about the nature of plasticity raised by Hebb and John, reviewed above. BMI experiments can spectacularly manipulate cellularto-population tuning curves, but the role of plasticity at the synaptic-to-cellular level (i.e., physical changes in synaptic structure) in these manipulations largely remains to be investigated (Legenstein et al, 2010;Koralek et al, 2012;Orsborn and Carmena, 2013;Orsborn et al, 2014).…”
